I noticed a bug using the recent version of logistic pipes that a provider pipe pulls out the requested item(s) but the crate keeps the item(s). I don't know anything about mod coding so I don't know if this is a bug on your end or logistic pipes but i thought i would bring it up.

wow very simplistic but usefull mod i really love it
and i suggest safes being able to be made of differend sizes and shapes (if you didnt think of that yet of course)
also i hope it gets added to secondary ftb packs not only for you also for me

At first, I didn't see the point behind crates. The realization that they work with item transport systems opened a lot of possibilities, though. Most of them involving a giant "warehouse floor" in a base, with a sorting system to get the items out. Shared inventory means less materials going to making individual supply routes for every storage unit on the system, and material efficiency makes me very happy. I also love the idea of different kinds of double-chests that can go next to eachother. The builder in me is most pleased.
